Analog Inputs
The PrimeLog has two types of analog inputs: general purpose and dedicated
integral pressure transducer.
General analog inputs may be voltage or current.
Voltage input range is nominally 0 - 21V DC. Voltages outside this range
require a special cable; standard voltage ranges available are 0 - 5V and 0 -
10V.
Current input requires a special cable suitable for 0 - 10mA, 0 - 20mA, and 4 -
20mA ranges.
If the logger starts before the sensor is connected, a malfunction will not
occur. However, the logger will register only zero values until the sensor is
connected.
Communication Link
The communication link is a cable that interfaces directly between the logger
and a PC/laptop serial port. Communication occurs at standard RS-232C
levels. You must configure the loggers through the PC/laptop before use.
The communications port on submersible loggers also is used for connecting
the Auxiliary Battery Unit.
